ROBERT A.. MINKS. OF DEWEY, ILLINOIS.

To all whom t may concern l Be it known that I, Renner A. Mmns, a citizen of the United States, residing at Dewey, in the county of Champaign and State of Illinois, have invented certain new and useful Improvements in Stack-Forming Apparatus, of which the following is a specification. i

As is well known to those skilled in the art, straw delivered from the pneumatic stacker of a threshing machine is scattered in a broadhalf circle thereby, and as the stack grows the straw continually slides down from the top, creating a wide base or foundation, which continues to increase as the pile.` increases. In order to avoid this, it is the usual custom to employ men to stay on the pile and shape it as it grows. This is disagreeable labor, and it is oftenuliflicult, if not impossible, to obtain the necessary 'workmen for the purpose.

Furthermore, it is the custom to allow the stock of the farmer to have access to the straw stack during the winter season. 'lhese feed on the same, and often undermine it, so that it frequently topples over upon the animals.

The primary object of the present invention is to provide an apparatus by which a stack can be e'ectively formed, and will maintain its shape without the necessity of the workmen being on the pile and arranging the straw thereof. i

A further object is to so` construct this forming apparatus, that part of it will constitute a permanent means for maintaining the stack andwill permit access thereto by the stock without i endangering the latter as above set forth.

In the accompanying drawing Figure l. is `aplan View illustrating the stack-forming ap]g aratus,

Figure 2 is a View in elevation of` a portion of the same on an enlarged scale,

Figure f3 is a vertical sectional View,

Figure @L is a detail View illustratingr one means that may he employed for mounting thc temporary posts,

Figure 5 is a view in elevation of a modilied form of construction,

Figure 6 is a sectional View at right angles to Figure 5,

Figure 7 is another embodiment of the invention.

In the structure illustrated two rows of posts 8 are employed arranged substantially Specication of Letters Patent.

wire fabric, preferably fencing, the serfctions being separable and detachable from the posts. These posts and fencifngI or wall sections constitute the" permanent portion of the apparatus. V

Temporarily associated with the posts t are higher removable posts iti). In the enibodiment illustrated in detail in Figure 4t, the permanent posts 8 are tubular, und 'the temporary posts detachably [it in their up per ends. The :fabric sections 9 are secured by detachable hoolt bolts ll. The posts l() have secured to their upper ends suitable pulleys l2. l/Vall sections i3, preferably of canvas or other heavy cloth, have secured to their upper corners, cables lelthat pass through the pulleys l', and may have their free ends fastened in any suitable u1annei'. Alords or cables l5, connected to the lower portions of the sections lil, serve as fastening means for the lower ends of said sections. The temporary posts l() may be braced by any suitable means, as for instance, stay cables 16 fastened to their upper ends. lreforably also end walls 17 are temporarily mounted on the end posts, as shown in Figure l. A

In use the permanent posts 8 are set at the poi ut where the stack is to be formed, and the wire sections 9 fixed in place thereon.

,l`he straw from the thresher is delivered intothe space between the inner and outer walls. llVhen this space has been filled the fabric wall sections 13 are placed in position. and are elevated as the stack grows. W'hen the stack is coi'i'iplete the temporary posts 10, wall sections r3 and end walls 17, are remo ved and may be carried with the thresher to the next ob, leaving the pile between the fence sections, which will hold it even thougl'i it extends a considerable distance thcreabo'vex It will be noted moreover that stock will have access only to the ends of the pile, and thus danger of the masses falling .upon them through undermining is obviated. [is the pile decreases, the sections 9 may be successively removed.

The temporary posts may be secured in place in various ways. Thus in Figures 5 and 6 the )ermanent posts 8 are solid, and

i have the Wire section 91 stapled thereto, as

shown at 1F. The temporary posts 10a are secured to the permanent posts 8a by suitahle yokes 12-, ln Figure "Z the permanent post is designated 8b and the woven Wire Wall section 9b. rEhe temporary post is shown at 10b and in this instance is bolted to the permanent post, as illustrated at lll.

l 1 rom the foregoing, it is thought that the construction, operation and many advantages oit the herein described invention will be apparent to those skilled in the art, Without iturther description, and it Will be understood that `various changes in the size, shape, proportion and minor details off construction may be resorted to Without departing; from the spirit or sacrificing any ot the advantages ot the invention. f

'.lilavingV thus 'fully described my invention, What l claim as new, and desire to secure by Letters Patent, is :h

l. ln stack forming apparatus, rows oli Vfixed posts arranged substantially on' arcs of concentric circles, sections ot ioraminous material detachably mounted on said posts, auxiliary posts adjustsbly earr'ed by the upper ends of said tired posts, means for securing' together the auxiliary and fixed posts, tabric sections detachahly connected at their lower edges to the lixed posts, pulleys on the upper ends ot the-auxiliary posts, and cables connected to the upper edges of said 'fabric sections and passing over said pulleys.

2. Stack formingvapparatus composed of ,sei

posts detachably connected to the lixed posts and adjustable vertically thereon, fabric wall elements 'forming a continuation of said flexible Wall elements and detachahly connected at their lower edges to the fixed l posts, and means for adjusting vertically the upper enges oit said fabric Wall elements as desired 3. Stack formingV apparatus composed of a permanent portion and a temporary portion; the permanent portion comprisinpr rows of ixed posts` flexible Wall elements detachalily carried thereby and meansl tor attachingil the flexible wall elements to said posts, the temporary portion comprising auxiliary posts adjust-ably carried by the fixed posts, means `For 'fastening` the auxiliary posts to the fixed posts, separate Wall elements 'forming` a continuation ol. said flexihlc nall elements, means ior attaching their lower edges to the ixed posts, means for vertically adjusting the upper edges ot said separate elements, and means for hracinfjr said temporary posts.

In testimony whereof l allix my signature in the presence ot two witnesses.
